The line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room. Thus, the scale factor of foot to inch is,
[tex]k=\dfrac{30}{12}[/tex]
Let suppose the line that represents the width of the room is 8 inches long, has the size of room in foot is x. Thus,
[tex]k=\dfrac{8}{x}\\\dfrac{12}{30}=\dfrac{8}{x}\\x=\dfrac{30\times8}{12}\\x=20[/tex]
Thus, the line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.

Which table represents a linear function that has a greater unit rate than that of the function y = 200x + 50?
Answer:
D
Step-by-step explanation:
A unit rate is basically which one increases more as time goes on. Now. to make it easier let me explain visual.
You have 50 apples at the start and every hour you get 200 more apples, sweet!
Now let's look at the chart.
The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.
Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.
Thomas has a bag with 6 purple and 5 blue marbles. If his friend Nick pulls 2 marbles from the bag, what is the probability of him getting 2 purple marbles. 30/121 30/121 21/22 21/22 3/11 3/11 11/21
Answer: 3/11
Step-by-step explanation:
Number of purple marbles = 6
Number of blue marbles = 5
Total number of marbles = 6 + 5 = 11
The probability of picking the dust purple marble will be 6/11. After a purple marvel has been picked, there'll be 5 purple marbles left and the total number of marbles will be 10, therefore the probability of picking the second purple marble will be 5/10.
Therefore we then multiply the probability of picking the first purple marble by the probability of picking the second purple marble. This will be:
= 6/11 × 5/10
= 6/11 × 1/2
= 3/11

If x=5 and the area of the rectangle is 30 what is the other length of the rectangle?
Answer:
The other length would be 6.
Step-by-step explanation:
Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6
You are saving for a bike and can save $10 per week. You have $25 when you begin saving. Write an explicit equation
to represent the amount of money you have saved at any given week.
Answer:
your pretty whatsbyour name
Answer:
Amount of money saved 25 35 45 55 65 75 85
Step-by-step explanation:
Explanation: On week 1 you have the $25 you already saved plus the $10 for that week, so $35.
For every week after that add $10 to the money saved for the additional $10 saved that week.
On the 8th week the total amount of money saved is 95+10, or $105.

if triangle GHI is equilateral and JHK is isosceles, what is the measure of JHK
Answer:
The measure of JHK is 25 degrees
Step-by-step explanation:
If GHI is equilateral, it means each of the angles are equal to 60 degrees
Thus;
7x - 31 = 60
7x = 60 + 31
7x = 91
x = 91/7
x = 13 degrees
The measure of JHK IS x + 12
simply insert the value of x here
Angle JHK = 13 + 12
Angle JHK is 25 degrees
Answer: 25

first to answer correctly gets brainleist! (bringing out a lot of questions so yea!)
Answer:
C.
Step-by-step explanation:
The easiest way to tell if a relation is a function is to look at the values of the x's. If more than one x is the same, it cannot be a function. In contrast, if more than one y is the same, it is okay. The answers A, B, and D are functions because the x's are all different. Looking at the table for the answer C, you can see that two x's are the same (there are two x's with the value of 1).

3 +5.2.c = 1 - 2.87
Answer:
-0.0936538462
Step-by-step explanation:
Start by solving the right side of the equation
1 - 2.87 = -1.87
now we have:
3 + 5.2c = -1.87
subtract 3 from both sides to get:
5.2c = -4.87
divide both sides by 5.2 to get:
-0.0936538462
